Hi Edgar, I have the same problem on a Toshiba laptop when I plug an external monitor. This laptop has an Intel P6100 cpu which is part of the 2010 Core family that integrates graphics on the cpu.
Did you solve the problem?

I'm not sure this is the right bug as it sounds like you are using an intel GPU.

This bug would probably be different for every GPU.

But if you are using a radeon GPU there are some fixes in the master branch that I haven't tried yet.

I was told on a different bug that it's a PLL issue.

I did not know if bugs were grouped by software or hardware, mine is an Intel GPU, so Ill search for other reports and create mine if necessary. Anyway, if you find your answer Id be very glad if you let me know. Thanks and have a nice day.

This looks like it could be a duplicate of #28306.
Comment 7 Ari Pollak 2011-06-17 16:25:58 UTC
Oops, I meant julio's problem would be a duplicate of that other bug.
